If you start taking thyroid replacement, you’ll want to watch for and report to your practitioner if you start to have any of the below symptoms after starting the replacement. My experience is that the standard lab test, called “TSH”, has to get below 1.00 before normal thyroid levels are achieved. This may falsely be interpreted as having too much thyroid hormone if all the doctor/nurse does is look at the lab report without questioning or examining you. That’s practicing bad medicine. If thyroid hormone is in excess, there are specific responses we see. This is why a complete physical exam and evaluation of your symptoms must be done. If you don’t have the symptoms, by definition, you can’t have too much thyroid hormone. If you do develop any of the symptoms below after starting thyroid replacement, stop taking your replacement and inform your practitioner.
